Weight and Mass Converter: kg, lb, oz, g & Stone
A practical mass converter for metric and common UK or US units, using the exact international pound relationship and transparent terminology.
Mass and everyday weight
Kilograms, grams, pounds, ounces, and stone are mass units in this converter. Everyday language often calls these weight, but physical weight is a force that depends on gravity.
The international avoirdupois pound is exactly 0.45359237 kilogram. One pound contains 16 ounces, and one stone contains 14 pounds.
Mass cannot become cups automatically
Grams and kilograms measure mass; cups and litres measure volume. Converting between them requires the density of a particular ingredient or material, so use an ingredient-aware Food converter for that job.
